Harmonization Code : 3506.10.00.00 | Prepared glues and other prepared adhesives, not elsewhere specified or included; products suitable for use as glues or adhesives, put up for retail sale as glues or adhesives, not exceeding a net weight of 1 kg
Main features
- 0.120-Inch Preformed Gap Control
- Compliant Low-Modulus Interface
- 2 W/(m K) Interface Heat Transfer
Product Description
Tflex B2120 is a 0.120 in ceramic-filled silicone thermal gap-filler sheet in the Tflex B200 family. Its low-modulus, compliant construction conforms to application surfaces, while typical 2.0 W/(m K) thermal conductivity transfers heat across the interface. The gray pad is naturally tacky on both sides for placement during assembly. Standard, center-fiberglass MFG, and one-side FG constructions are available within the family for different handling and reinforcement requirements. The material also has typical volume resistivity of 2 x 10^13 ohm cm and a -40 to 150 deg C temperature range.
Key features
- 120-mil sheet: 0.120 in preformed Tflex B200 grade.
- Compliant interface: Low-modulus construction conforms to application surfaces.
- Dual-side tack: Natural tack on both sides supports placement during assembly.
Applications
Applications include automotive electronics, gaming systems, instrumentation, routers, wireless infrastructure, and portable devices.
